Paralithodes brevipes (ハナサキガニ, Hanasakigani),[2] also known as the spiny king crab and sometimes the brown king crab,[3] is a species of king crab.[1] It has a limited distribution in cold, shallow waters as far south as the coast of Hokkaido,[4] where male-only fishing has damaged the reproductive success of the species,[5] up to as far north as the southwest Bering Sea.[6]

They are known to be parasitized by Hematodinium.[7]
Reproductive behavior
editMale P. brevipes guard females prior to copulation, spending less time doing so when females are more numerous.[8] The reproductive success of the species is heavily sensitive to the ratio of male to female crabs.[8][5] Because sperm recovery in P. brevipes occurs at a slow rate, males allocate sperm dependent on the size of the female.[9]
